Short Description

I couldn't get a small file of the IQ. However, this frequency's always populated with evenly spaced lines of just that, and it typically forms something like this at large:

It's always active in my area, but I can never find any program that can decode it. It sounds like someone's just sending tones over the frequency, but it also looks digital.

Audio Sample

99% chance this is noise from your computer. Computers are awfully noisy. - 1/14/19

Damn, is it? My antenna's about a meter away from my computer, at the farthest I could put it. I see this frequency on other frequencies and it always seems to shift around. - 2019年1月21日, OP

Check the file again...and try to upload again...

I used to live in VB and heard lots of unknown signals...possible from Oceana? 73's

Probably from monitors near the antenna. Try turning your Monitor off/on and see if the waterfall changes
